Changes are coming to federal and state air quality regulations affecting new and existing upstream and midstream natural gas operations. Congress is in the midst of finalizing legislation to undo a Trump administration Clean Air Act (CAA) rule, which rolled back Obama-era CAA requirements. Separately, the U.S. Environmental Protection Agency (EPA) has begun developing rules for existing air emissions sources within the natural gas sector. At the state level, the Pennsylvania Department of Environmental Protection (PADEP) is poised later this year to finalize its own set of air regulations for existing sources within the natural gas sector. Any of these regulatory developments alone would be noteworthy; combined, they likely signal increased oversight, scrutiny, and regulation of new and existing air emission sources within Pennsylvania’s natural gas sector.
Congress Set to Disapprove Trump EPA Oil and Natural Gas CAA Rule
In March 2021, Congress invoked its rarely used Congressional Review Act (CRA) authority to rescind a Trump EPA rule that excluded emission sources in the transmission and storage segments and rescinded methane emission limits for the production and processing segments in New Source Performance Standards for the Crude Oil and Natural Gas Industry at 40 C.F.R. Part 60, Subparts OOOO and OOOOa (NSPS). Oil and Natural Gas Sector: Emissions Standards for New, Reconstructed, and Modified Sources Review, 85 Fed. Reg. 57018 (Sept. 14, 2020). Reinstating the NSPS methane requirements means that EPA would be statutorily required to regulate methane emissions from existing affected sources within the natural gas sector. See 42 U.S.C. § 7411(d)(1).
While U.S. Senate voted to pass a joint resolution revoking the Trump administration’s revisions to these NSPS in April 2021, a vote in the House of Representatives has yet to be scheduled. …
